To all whom it may concern:

Be it known that I, ADAM; Triton, a citizen of the United States, residing at Sloan, in the county of Erie and State of New York, have invented certain new and useful Improvements in Runners for Baby-Carriages; and Idohereby declare the following to be a full, clear, and: exact desoriptlon of the invention, such as will enable others skilled in the art to which it appertains to make and, use the: same.

This invention relates to a runner. structure adapted for use on baby carriages and the; primary object of the invention is to provide a runner'structure which has wheels carried thereby, so that. the wheels may be moved into operative position,v when. the car.- riage is moved in: a-house, or over. places 1n the. sidewalks or street where there is no snow, and further toprovide a pair of p1v. oted, arcuate' levers; which. carry the wheels, and have connecting rods connected thereto and tea lock structure through themedium of which look structure thewheels are moved intooperatiive positions, or-allowed to move upwardly out of operative posltlonsorthat the weight of thecarriagewill be borne by the runners in lieuofbythewheels.

Another objectof this invention is to pro vide a runner structure asa'specified, which may beattached. to any baby carriage by the one of the axle carrying boxes or bearings 01: therunner.

VVi-th theforegoing and other 01)]QGlZSl11 View, this invention consists; of] such novel features of. construction, combination and arrangement of parts will be hereinafter morelfully described, illustrated in the accompanyin drawings and; claimed.

In descri ing theinventlon 1I1:Cl8t2t1lI:8ference. will be. had to the accompanying drawings wherein like characters designate like and corresponding.- parts throughout the several views, .ancl:.,in which Figure l is a side clevationof therunner structure, showing a part of azbaby. carriage mounted thereon and-illustrating the. rollers orwheels in operative weight supporting position. d 1

Fig. 5: 1s adetail perspective view illus bra-ting the manner of adjust-ably connecting the bearing bracket to the runner structure.

Referring'more particularly to the drawings,,1 designates the runner of the runner structure; which runner is constructed ofbar iron, and has its rear end 2 curled, as clearly shown. inFigs. 1 and 2' of the drawings, so as to provide a rounded rear end to the run ner aswell as add to the artistic appearance of the runner structure. The forward end '3 of the runner l is also curved upwardly and spirally curled at its terminal so as to provide a comparatively high rounded surface or'f-ront end to the runner. The highest part of the curved front end 3 of. the runner is positioned a comparatively short distancebeneath the springs as indicated at 4 of an ordinary baby carriage 5 and the curl or spiral 6 at the terminal of the front end 3 is attached in any suitable manner to the front end of the brace or supporting bar 7 of the runner structure. The brace or supporting bar 7 of the runner structure has a bearing box 8 carried by its upper surface at its forward end and a second bearing box 9 carried by its upper surface adjacent to its rearend. The bearing boxes Sand 9-are provided for receiving the spiudles of the axles of the baby carriage 5, for connecting the baby carriage to the runner structure. 7

The bearing box Sis adjustably mounted of the. bracing bar 7, audit is held in various adjusted posit-ionsthrouglithe medium of set screws '10, which engage the upper surface of the bar 7 and force the cross-bars 1.0 infirm en- 'agementiwith the under surface of the bar The crossbars 10 are formed upon the Fig. 5 of the The. adjustment of the bearing provided for regulating. the distance betweenthe bearing boxes 8 and9 to accommod'atethe distance between the axles ofi'vari'oustypes of baby carriages.

V The-runner l. is provided with. a forward indentation orup'stan'din portion 12- andla real: indentation or upstanding portion 1-4. Theip'ortions 12: 3. 11651% are .forniediby} benddrawing.

rollers 15 of the runner structure. 7

ing portions of the runner 1 upwardly to form substantially inverted U-shaped por-. tions in which are positioned the wheels or The wheels or rollers 15 are comparatively small with respect to the usual type of baby carriage wheels and they are carried by the lower ends of arcuate levers 16 and 17 respectively. The levers 16 and 17 are pivotally connected as shown at 18 to the runner structure 1 and they have connecting rods 19 pivotally connected to their upper end as shown at 20. The connecting rods 19 extend toward each other, and have their inner ends connected to a safety lock structure 21. The safety lock structure 21 is provided for holding the rods 19 in horizontal positions, against accidental pivotal movement, for holding the wheels 15 in load supporting positions, as indicated in Fig. 1 of the drawings. When the rods 19 are positioned in horizontal planes, the rollers 15 will project beneath the under surface of the runner 1, as clearly shown in Fig. 1 of the drawings, so that the weight of the baby carriage 5 will be supported by the wheels and so that it may be readily and easily pushed over surfaces where there is no snow or ice, such as in a house, or over places on sidewalks or streets where the snow has been removed or melted.

The safety lock structure 21 comprises casing 22, in which the upper end of the bars 19 are pivotally mounted as shown at 20*. The bar 19, which is positioned to the front of the carriage, has an angled bar 22 carried thereby, one arm of which extends at right angles to the bar 19. The bar 19, which extends toward the rear of the cart, has an arm 22* connected thereto which is curved, as clearly shown in Figs; 3 and 4 of the drawings so as to provide a guide 7 for the inner end of the pivotally mounted position,

lever 22. The lever 22 is pivotally mounted upon a pin 22 and it projects out-of the casing 22. A coiled spring 22 is connected to the arms 22 and 22, and a second coiled spring 22 is connected to the forwardly extending arm 19 and to the arcuate arm 22*, as clearly shown in Figs. 8 and'4 of the drawing. The springs 22 and 22 are provided for facilitating the movement of the bars 19 into the position illustrated in Fig. 4, upon the depression of the outer end of the lever 22*. A lug 22 is formedupon the lever 22 and is provided for engaging the lower end of the angled arm 22 when the wheels 15 are held in ground engaging position, and a second lug 22 is also carried by the lever for engagement with the depending arm of the angled arm 22 when the wheels 15 are out of a ground engaging as shown in Fig. 4. A stop pin 22 .is carried by the casing 22 for limiting the outward movement of the pivoted lever '19 may force snow 22 A flat spring 22 is connected to the lever 22 and has one end inserted into the coiled spring22; The spring 22 is provided for facilitating the operation of the pivoted lever 22".

The top 22 with openings 22 through which the 'bar in case the casing becomes filled with snow.

The lever 22 is provided for controlling the locking of the rods 19 so that when itis desired to support the weight of the carriage 5 by ated which releases t and allows the weight of the carriage to force the runners downwardly, which move the connecting rods 19 outwardly at angles, with respect to each other, as clearly shown in Fig. 2 of the drawings. otal movement of the arcuate levers 16 and 17 under which'movement the wheels 15' move upwardly within the substantially inverted U-shaped portions 12 and 14, so that the runner structure 1 will rest upon the surface over which the carriage istraveling, and support the weight of the carriage.

Suitable braces, indicated at 23, 24 and 25 are provided, for supporting the bar? of the casing 22 is provided This allows 'pivin proper spaced relation with respect to the runner l, and these braces are shaped so as to provide the greatest supporting strength, for their size and'also so as to add to the artistic appearance of the runner structure, certain of the braces being curved or curled as shown at 26. A brace 27 is attachedfto the front curved end 3, of the the curl or spiral 60f the vature thereof as clearly shown in Figs. 1 V 110 r and 2 of the drawings; This substantially S-Shaped blade 2'? I braces the construction the front curved portion of. I

runner, and it is substantially S-shaped, be-

of the front end of the runner, and also adds to the artistic appearanceof the same.

The safety stop structure 21 has'an angled' plate 28 attached thereto, the horizontal portion of which projects outwardly beyond the edge of the runner 1 and the bar 7 so that the person pushing the car-- riage may place their foot upon the hori- V zontal portion and press downwardly thereon for moving the rods19 into'horizontal positions, and the wheels 15 into load supporting position. 7 When it is desired to,con-. vert the baby carriage into a sleigh or sled,

pressure is applied, by the operators foot upon the lever 22 which releases the lock ing mechanism and allows the rods 19 to move, as previouslyspecified;

In reducin theinvention'to practice," .1-

tain minor eatures of construction, combination and arrangement of parts may necessitate alterations to which the patentee is entitled provided such alterations are comprehended Within the scope of What is claimed.

What is claimed is In a device as set forth, a runner, means for connecting said runner to a baby carriage, said runner being constructed of bar iron and bent intermediate its ends to form a forwardly positioned substantially in verted U-shaped portion and a rearwardly positioned substantially inverted U-shaped portion, a pair of arcuate levers pivotally carried by said runner structure and having their lower ends extending into said inverted U-shaped portions, Wheels rotatably carflopiee of this ried by the lower ends of said arcuate levers and positioned Within said inverted U-shaped members, connecting rods connected to the upper ends of said arcuate levers, and a safety lock structure c011- nected to the inner ends of said connecting rods and adapted for holding said connecting rods against accidental movement for holding said Wheels in a load supporting position.
